| Intense residual erosion attacks several sections of the Belgian coast. During the last decades this coast has been hit over several kilometers at Knokke, at Bredene-De Haan, at Lombardsijde, at Koksijde and at De Panne. A sequence of beach budgets shows the phenomenon and its importance and proves that different morphodynamic sections follow one another all along the rectilinear coast. The author ascribes every erosive section to an erosive megaprotuberans attacking the coast over a more or less long distance during a more or less long time span. He proves that such megaprotuberans develops gradually, that it is part of a cyclic macroprocess of coastal evolution that lasts several decades, sweeps the cost and whose aggressive phase is followed up by a... |
